The 58 contains a knot similar to the Duke 3 Manchurian, but housed in a longer handle.
The Jubilee feels soft and pliable.
The 58 feels more compact, retentive of shape and provides feedback against the face, that many have come to describe as "scritch."
Scitch to me is the sensation arising from the strength of individual hairs resisting or pushing against the skin rather than collapsing as would a weaker hair or irritating and scratching the skin as with a coarse hair.
Scratch in my opinion is entirely different to scritch and for me is not a coveted attribute.
The Jubilee's softness compared to the 58 may be attributed to the fact that it is slightly less densely packed.
Although visibly this difference is challenging to observe, when employed to lather directly on the face the difference in sensation is remarkably noticeable.
Remarkable in that the knot, rather than the individual hairs themselves behaves (presumably due to construction or packing) in a slightly different manner providing for albeit a small, but entirely different experience.
Sat side by side the handle of the Jubilee is dwarfed by the 58, but both handles are extremely comfortable to hold.
The size of the Jubilee handle is certainly more suitable for face lathering, while the 58 would definitely cater for bowl lathering if that was your preference.

Manchurian closely resembles 2 band in appearance and characteristics. However, it feels and behaves somewhat more akin to a softer 3 band and is not quite as dense. The 2 band derives much of it's backbone from the combination of hair grade AND the volume of hair packed into the knot. Manchurian relies more on the strength of the individual hair to provide backbone. The benefit of this, is improved flow through due to less density and it blooms a little more. The Manchurian quickly adopts a more hybrid shape rather than retaining a more bulbous shape like the 2 band. This also gives the Manchurian a bigger feel compared to the more concentrated 2 band knot. The Manchurian tips are soft, but provide some sensation due to the resistance they provide against the skin, rather than buckling under pressure like the 3 band does. I believe this is the basis of debate over which is softer. IMO the Manchurian has softer tips, but provides sensation at the same time due to it's strength.

The Manchurian and 2 band are close no doubt, but the Manchurian for me excels in many key areas including, backbone, density, flow through, softness and sensation. Describing the Manchurian is almost contradictory at times, but perhaps best understood as having the right amount of everything.

There are brushes that are softer, there are brushes that are scritchier, less dense more dense etc etc. The thing that these brushes have in common is that they tend to only possess a single characteristic in abundance. Where the Manchurian seems to have it all. Softness, but with sensation. Dense feel, but with flow through. And so on.

Overall the differences between 2 band and Manchurian are small, but they do seem to make a world of difference!

Thank-you Arash, but that's just my opinion. Of course it's always a case of YMMV and even with the Manchurian hair grade, differences in knot construction are going to provide subtle differences in experience. Take the Jubilee for example, which has almost universally been agreed upon as being somewhat softer than other Manchurians - that's the fun thing about badger - so many variables! My best advice is to try one for yourself! My experience and explanation is always going to be different to the next person's and thats the great thing about people -we're all different and experience things differently and interpret those experiences differently and then explain those differences differently...
